Specification of Letters Patent. Application filed May 14.1907. Serial No. 373.648.

Patented Dec. 3, 1907.

To all whom it may concern: 1

Be it known that I, ISAAC R. MATTHEWS, a citizen of the United States, residing at Barnesville, in thecounty of Pike and State of Georgia, have invented certain new andthe provision of a door check or retainer constructed and arranged for disposition in the path of movement of the door so that when the door is opened it may engage the checkor retainer and be automatically heldin its open position with a minimum of frictionalengagement between the door-and check or. .retainen.

With the above and other objects in view,

the present invention consists in the-combination and arrangement of parts hereinafter more fully described, illustrated in the ac-.. companying drawings," and". particularly pointed out in the appended'claims, it being understood that changes may be made in the form, size, propo'rtion, and minor details without departing from the spirit orsacrific- -ing any of the advantages thereof.

In the drawingst'-Figure 1 is a fragmentary perspective view of the door frame and door in its open position and in engagement with my improved door check or retainer. Fi s. 2, 3 and 4 are diagrammatic plan views indicating themanner of operation of the invention in several of the positions assumed by the device when the door is moved into enga ement with the same.. Fi 5 is a sectiona view on the line a,a of ig. 1.

My improved door check or retainer embodies such characteristics that there is very little friction between the same and the door when they are engaged one by the other, and

the door'is, designed to move the check or retainer'into cooperative relation therewith mit closing without the instrumentality of one or more projections upon the door.

The device is of such character that itmay be used with anydoor without separate or 1 it might'be intermediate connections.

Before entering into detail stated that the invention consists essentially of a curved body member pivoted intermediate its ends and provided at each end with a roller so mounted that it msifrotate upon its pivot simultaneously with a movement -of the body of-the check or retainer, the rota-= tion of the rollers and simultaneous movement of the body being accomplished by the door, and the door being held securely in its open position until the check is manually op era'ted to permit closing of'the door. .To permay-be e aged by ones foot to be shifted o ut of use ecking or retaining-position.

: he. accompanying drawings, the refer ence-character 1 indicates a door and'2 the body portion of my invention, the body por of'the door the check or retainer .tion being preferably curved, arcuateinshape i or as shown, and. pivotally connected to t e floor intermediate its ends thrdugh the instrumen'tality of p a screw or other suitable ivot connection 3. A perforation is formed n each end of the curved body 2 for the reception of the reduced end 4 of the posts 5.-

These posts 5 are designed toform bearings for the support of the rubber or other rollers 6, which may be slipped upon the posts-5 and readily removed therefrom.

In the use of my invention, it is placedat' opening movement to pass the first roller 6 and engage the opposite roller, the striking of the opposite rollerby the door causing the first knob to be thrown behind the door,

leaving the freeside edge of the door between the rollers until released, whereby the doc cannot accidentally close.

I While the rollers6 fit comparatively tight upon their bearings, they do have movement thereupon, so that when. the door strikes the rollers they may-move simulta- H neously with a bodily movement of the body thereof upon their pivot. By reason of the simultaneous rotation of the .engagedrollers' e5 such an angle as to permit the door in its:
